fan will not turn off

[lewma]

NEW question:
I've seen it stated on this forum that some fans will not turn off at idle, so as to keep them from cycling on and off while at a stand still. Does anyone know if this is true?, or how to tell, or at what speed needs to be achieved to turn the fans off? Or was what I read just a bunch of C__P.

If the ECU needs VSS to learn vehicle speed to turn off the fans then it's possible that the fans will not turn off if you're idling. Go take it for a drive and see ?

I have stated this and even specified on which controllers this option is activated.

And on the verge of the fourth page of this thread there is still no log...

can you extrapolate. I've looked for this, but can not find the info

is this K_FanSpdChgIdle switch-calibration something that can be accessed with HP Tuners???? or does one need a Tech II at the dealer?

It's in a table that isn't defined in HPT. And I doubt that it is adjustable with a tech II, but maybe? Thos with enough skills can access and define additional tables through other program.

This is because verlon and hjtrbo have tech skills that most of us do not have. They are looking at the raw binary/hex code from the ECM. HPT only gives us insight in to like 1% of the ECM and TCM. If you want to go deeper you have to reverse engineer the machine code. Not an easy task.

Or just, you know, use an OS (or segment) that works with the hardware you want to use.
